Dilaudid (hydromorphone) is classified as an:

Choice A reason: Label away aids reading, but thumbnail ensures dose accuracy. This errors per nursing standards. It’s universally distinct, less precise than thumbnail method.

Choice B reason: Thumbnail on cup line guarantees exact liquid dose poured. This aligns with nursing pharmacology standards. It’s universally applied, distinctly accurate for administration.

Choice C reason: Returning surplus risks contamination; thumbnail prevents overpouring. This choice misaligns with nursing safety. It’s universally distinct, unsafe for medication handling.

Choice D reason: Below-eye level risks misjudgment; thumbnail is precise. This errors per nursing pharmacology standards. It’s universally distinct, less accurate than standard.

Choice A reason: Rectal is enteral, using the GI tract for absorption. Vaginal isn’t enteral. This fits nursing pharmacology standards. It’s universally distinct, part of digestive routes.

Choice B reason: Nasogastric delivers to stomach, an enteral method clearly. Vaginal differs entirely. This aligns with nursing standards. It’s universally distinct, a GI route.

Choice C reason: Vaginal is topical/mucosal, not enteral like GI routes. This is the exception per nursing pharmacology. It’s universally distinct, outside digestive administration methods.

Choice D reason: Oral is enteral, absorbed via digestive system typically. Vaginal isn’t included. This matches nursing standards. It’s universally distinct, a core enteral route.
